解析JSON对象的JavaScript
您好所有我有一个JSON对象像解析JSON对象的JavaScript
{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}
,我想分析它像
[ {
title: 'All Day Event',
start: new Date(y, m, 1)
},
{
title: 'Long Event',
start: new Date(y, m, d-5),
end: new Date(y, m, d-2)
}]
我将如何做到这一点。我写了这个代码,但它得到安宁数组长度0我的代码是
var response = eval(data); $.each(response, function() {
obj = {};
$.each(this, function(k, v) {
if(k=="start")
{
obj[k] = new Date(v);
}
if(k=="end")
{
obj[k] = new Date(v);
}
else
{
obj[k] = v;
}
event_data.push(obj);
});
});
回答:
data = JSON.parse('{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}') arr = []
for(var event in data){
var dataCopy = data[event]
for(key in dataCopy){
if(key == "start" || key == "end"){
// needs more specific method to manipulate date to your needs
dataCopy[key] = new Date(dataCopy[key])
}
}
arr.push(dataCopy)
}
alert(JSON.stringify(arr))

看起来你已经在使用jQuery所以只需使用$ .parseJSON。 (http://api.jquery.com/jQuery.parseJSON/)
您必须迭代创建的对象才能将日期字符串转换为Date对象。

var data = { "event1": {
"title": "My birthday",
"start": "12\/27\/2011 10:20 ",
"end": "12\/27\/2011 00:00 "
},
"event2": {
"title": "My birthday again",
"start": "12\/27\/2011 10:20 ",
"end": "12\/27\/2011 00:00 "
}
};
var response = eval(data);
var events = [];
$.each(response, function(key, event) {
var obj = {};
for (var prop in event) {
obj[prop] = event[prop];
}
obj["start"] = new Date(obj["start"]);
obj["end"] = new Date(obj["end"]);
events.push(obj);
});
console.log(events);

我的代码:
var datas = '{"event1":{"title":"My birthday","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "},"event2":{"title":"My birthday again","start":"12\/27\/2011 10:20 ","end":"12\/27\/2011 00:00 "}}'; var dataObj = eval("(" + datas + ")");
var finalArr = [];
for(var i in dataObj) {
var t = dataObj[i];
finalArr.push({
title: t.title,
start: new Date(t.start),
end: new Date(t.end)
});
}
console.log(finalArr);

收集数组的所有项目,并返回一个JSON对象 - 这个代码是基本的一个选择框的所有值..但你可以根据你的要求修改它。
collectData: function (arrayElements) { var main = [];
for (var i = 0; i < arrayElements.length; i++) {
var data = {};
this.e = arrayElements[i];
data.text = arrayElements[i].text;
data.val = arrayElements[i].value;
main[i] = data;
}
return main;
},
解析,我们通过这样下去
dummyParse: function (json) { var o = JSON.parse(json); //conerted the string into JSON object
$.each(o, function() {
inner = this;
$.each(inner, function (index) {
alert(this.text)
});
});
}

相同的数据也许这个方法没有5年前存在。但是如果你想美化你的JSON数据或只是一个简单的JS对象,只需要在日志中使用JSON.stringify()就足够了。
输入
let cat = { name: {fist: "Fluffy", last: "LaBeouf"},
color: "White"
}
解析
JSON.stringify(cat, null, 2)
输出
{ "name": {
"fist": "Fluffy",
"last": "LaBeouf"
},
"color": "White"
}
注意:在字符串化方法2是NU大量的空间。
